RNA polymerase II
RNA polymerase II
(
RNAP II
and
Pol II
) is an
enzyme
found in
eukaryotic
cells. It catalyzes the
transcription
of
DNA
to synthesize precursors of
mRNA
and most
snRNA
and
microRNA
. A 550
kDa
complex of 12 subunits, RNAP II is the most studied type of
RNA polymerase
. A wide range of
transcription factors
are required for it to bind to upstream gene
promoter
s and begin
transcription
.
